Frequency of allergic diseases following measles
Published in Allergol Immunopathol (Madr). 2006;34:146-9. - vol.34 núm 04
Abstract
Objetivo: Las infecciones virales y bacterianas durante la niñez disminuyen la probabilidad de enfermedades alérgicas en los años posteriores. Sin embargo, a pesar de los trabajos sobre la baja frecuencia de enfermedad alérgica en pacientes con historia de sarampión, algunos estudios todavía sugieren que esta enfermedad puede causer un incremento de la frecuencia de patología alérgica. El propósito de este estudio fue investigar la frecuencia de enfermedades alérgica acaecidas después del sarampión. Métodos: Cincuenta y dos niños con sarampión hospitalizados en nuestra clínica, fueron comparados con otros 51 que no padecían la enfermedad. En ambos grupos se investigó la enfermedad alérgica por medio del cuestionario ISAAC. A todos los niños se les practicaron pruebas cutáneas a los cuatro alergenos más comunes. Resultados: La sensibilidad a D. pteronyssinus fue menos frecuente en niños con sarampión
(p<0.05). La administración de salbutamol nebulizado en el servicio de urgencias en los 12 meses anteriores fue también menos frecuente en el grupo con sarampión (p<0.05). El uso de corticoides inhalados fue más común en el grupo sin sarampión (p<0.05). Conclusiones: Los resultados de este estudio indican que la incidencia de enfermedades alérgicas es menos frecuente en niños con historia de sarampión. En un menor porcentaje de estos niños se demostró sensibilización al D. pteronyssinus.

Introduction
INTRODUCTION
The
prevalence of allergic diseases is steadily increasing in our
country similar to the increase throughout the world
1-4. Allergic diseases are known to be more frequent in
Western countries 5-7. Similarly, the prevalence of
atopy diagnosed by the skin prick test and specific IgE is also on
the increase 8,9. These findings may be attributed to
the hygiene hypothesis, which suggests an increase in the frequency
of atopic diseases due to the decreasing number of children in
families and a fall in the number of infections 10,11.
According to this hypothesis, the cytokine profile with an innate
predominance of allergenic Th2 profile, shifts to the
non-allergenic Th1 profile with the influence of childhood
infections 12,13. Although a number of studies
demonstrate that measles and other viral infections prevent
allergic conditions, other reports suggesting an increase in
allergic diseases due to these infections are also present
15-20. Turkey is a country with a high prevalence of
childhood diseases. The number of measles cases was 30,509 in 2001
and the morbidity rate was 44.97 per one hundred thousand
21.
We aimed to
investigate the correlation of allergic diseases with a history of
measles.
METHODS
Fifty-two
children with a diagnosis of measles who were hospitalized in the
Pediatric Infectious Diseases Clinic in the Okmeydan Teaching
hospital during 1996 and 2002 were incorporated into the study. The
control group consisted of fifty-one children who had been admitted
to the outpatient clinic for other...
